Designed specifically for Mercury and Mariner high-performance racing outboards, including SST-120 and S3000 series V6 2.0L, 2.4L, and 2.5L engines, this starter features a 10-tooth clockwise (CW) rotation Bendix drive matched to a 100-tooth flywheel ring gear.

It is used in counter-rotation racing outboards and is critical for proper torque delivery and engagement precision.
